Q.
A string of length $7m$ has a mass of $0.035kg$ . If tension in the string is $60.5N$ , then speed of a wave on the string is
NTA AbhyasNTA Abhyas 2022
Solution:
speed of a wave on the string is,
$v=\sqrt{\frac{T}{\mu }}$
Linear mass density is, $\mu =\frac{0.035}{7}$
$\mu =5\times 10^{- 3}kg/m$
$\therefore $ $v=\sqrt{\frac{60.5}{5 \times 1 0^{- 3}}}$
$v=\sqrt{12.1 \times 1 0^{3}}$
$v=110m/s$
